He is trained by Buddy McGirt, we all know what that means....doomed. In the last 5-6 years, having McGirt in your corner means a guaranteed loss. I appreciate that this irishman is a warrior but he is going to lose and take sustained beating while doing so. I am no fan of Sergio to be honest, but the guy was able to take the best shots from Cintron, Williams and Pavlik and never was hurt. Good luck on St. Pattys day for Macklin but no way I see him winning this. Unless a miracle happens, this guys either getting stopped in mid/late rounds and losing a UD. Sergio reminds of RJJ back in the day a little bit, what I mean is, from a reflex perspective. Until Sergio's reflexes slow down, I do not see many people, if anyone, beating him at 154-160. Also, the equalizer is Sergio has 1 punch KO power it seems, so that is always dangerous. If Macklin can somehow pull it off though, good for him.
